You need to use a cleaner first before the sanitizer. Something like one step, PBW, oxyclean

FWIW I put up a similar post last week and got all sorts of responses. Essentially in order to get rid of any trace of odor I had to agitate and soak each keg (and all of the parts) in a 5 gal solution of boiling water laced with oxiclean detergent over a 24 hour period, rinse clean with hot water twice, and then sanitize it for 24 hours in 5 gal of idophor/water solution. It was a huge job.

That alone did not do it however, in order to completely remove the odor I had to do this process all over again since it did not work sufficiently the first time.

Needless to say this seriously sucked but now all I smell now is the idophor.

I wonder if Washing Soda (sodium carbonate) would do the trick? It's a great cleaner, but I don't know if it removes odors. It's caustic, about ph11, so gloves and eye-protection are recommended. I may try that with my kegs, which I recently bought from CHI but haven't cleaned and rebuilt yet.

In household deodorizing (getting the smell out of food containers) I have found that a strong solution of Baking Soda and Water will absorb most smells, just let it sit for a few days...and use a lot of baking soda.

I've done it successfully with my cooler mlt, after my nasty mishap with the GAP experiment, it got that burnt, sickly sweet smell right out.
